To all wheat it mar concern Be it'known that 1, O'rrs zenof the United States residing at Sal1sbury, in" the'county of useful Building nits; and I do declare the following to be a full, clear, and exact descripture is formed, the units may be put in place and these units held firmly together so that they cannot movetransversely of each other and to further soconstruct these units that if desired, cement may be poured between them and thus prevent leakage between the units.

Another object bf the invention is to so construct these units that each may be pro-:

vided with a pair of anchoring strips which will bet-firmly held in place and will extend at substantially right angles to each otherf and to further provide each unit with-a pluralit of rooves. for re'ceivin anchorin I strips carried by other units,- these grooves being so positioned that a unit may: be put' in place in aselected relation to a' unit'already in placeand thus a straight wall pro-' vided or if so desired avturn made at almost construct these units that they ma be taken apart if so desired or may-be le t in place and provide a very strong and solid structure which will not be liable to come apart. This invention is illustrated .in the ac-- companying drawings, wherein Figure 1 is a-top plan view number of the units assembled to form a wall havinga turn provided therein.

his building unit or pile will'be' formed." 1 i of cement and as shown will be-substa'ntially ,V -shaped in cross-section or top plan. Each 'of the' units will be formedthe necessary length according to the work to which it is to be put, 1t belng understood that a unit I used for building a cotter-dam would have to be longer than a unit used'in buildin' a sea' wall. These units have been indicate in i general by the numeral 1 although each is substantially V-shaped'in top plan or crosssectlon, 1t should be noted that theyare relatively thick so as 'to provide inner and outer side walls 2 and 3- which extend paraling relation and have their outer ends connected .by end walls 4. The outer walls 3 are not extended in converging relation a .sufiicient distance to meet but instead are connected either by a flat surface 5 as shown in Fig. 6 or'by means of a trougha I *shapedsurface as shown in Fig. 3. "From an inspection of Fig. 1, it will be seen that when these, units are put together,-the fiat,

.lel as'shown in Figs. 3 and Sand in convergface 5 or trough-shaped face 6 will leave al '3 space 7 between-the units so that cement .which is to form a binder may be poured into these spaces and .when set serves to provide a filleli between the units to eflI'ectiveIy Y prevent the passage of water between them I and further serves as a blnder to securely hold i The outer side faces3 and the'end faces 4 are provided with longitudinally extending grooves -8' which are spaced an equal distance from adjacent I These to recelve the strips 9 of adjoining units so that when the units are put together they grooves 8 are will be held against transverse movement and thusprevented from pulling apart. The

"strips 9 are embedded inthe units and extend from the inner side Walls 2 thereof at substantially right angles to eachother and are showing a spaced from the adjacent corners a distance equal to*- the distance between the grooves 8 and'adjacent corners. Therefore,the units may be'put together with the ribs or strips 9 of a unit fitting into a selected pair of grooves ofanother unit. This is fully brought out in F ig. 1 where the units are shown assembled in varying specific rela- 'tions'to each other. These strips 9' may be formed of metal or may be formed of wood I wood with the grain. extending outwardly each of these strips is provided with a longitudinallyextending groove 10 so that when 1 i .the units are molded with the strips embedded'in the soft cement or' concrete, the material from which the'unit is formed will" flow into'the grooves of these strips and the strips, thus securelyheld in lace and prevented from working loose. hen the place and another will then be placed with its lower end adjacent the upper end of the 1 one already put in place. The strips 9 of the second unit will then be guided into the upper end of a selected set of grooves 8 of the unit already in place and the second unit will. then be driven downwardly with the strips 9 in the selected set of grooves. When this second unit-is in place, additional units can then'be put in place and a' straight wall v formedor as shown in Figx'l a turn made in the wall at the angle shown or at other possible angles. If the units are being formed to construct a cofl'er-dam or other similar structure which'it is desired to take apart and remove, the units can be grasped by a suitable device when it is desired to take the structure apart and the units drawn upwardly out of place. If it is desired to provide a structure which will be very water-tight or provide a structure where it is desired to have the units firmly held inyen-- gagement with each other, thin cement can be poured into the openings 7 which will be formed so that this cement will provide a filler which will prevent water from working through and further serve as a binding to hold the units't'ogether. There has thus been provided a building unit so constructed that the units cannot have transverse movement when assembled as the strips 9 of eachunit extend at right angles to each other and y will thus serve to hold the units against movement in two directions.

I claim: 1. A building unit V-shaped in top plan and having its arms extending in diverging relation to each other, the arms having their tending from the same at substantially right ends. and outer side provided with longitudinally extending grooves, and strips extendingfrom the inner side faces of the i units are assembled, one will be driven int0 l0ngitudinally extending ribs projecting at Q right angles to each other'for fitting into selected. grooves'of another'unit.

.3. The structure of claim 2 having the corner portion opposite the removed quarter section cut awayto provide restricted spaces between assembled units. i

4. A lastic building unit substantially V-shape in cross section and provided with longitudinally extending grooves, and strips extending longitudinally of the unit and exangles to each otherfor fitting into selected grooves of another unit, the embedded portionsof the strips being provided with lon itudinally extending grooves to receive t e pi'astic of the unit and hold the strips inp ace. v

5. A building unit substantially V-shaped in cross section and having relatively wide arms to'provide inner and outer corners at the ends thereof, said unit havin its side faces provided with groovesexten ing from the upper and lower ends and positioned 'equi-distant from adjacent corners, and ribs carried by the unit for fitting into selected grooves of an adjoining unit and extending at substantially right angles to each other to hold the units interlocked against transverse movement. I c

.6. The structure of claim. 5 having the corner portion at the junction of the outer side faces cut away to provide restricted spaces between adjoining units when put to ether. l

n testimony whereof I have hereunto set my hand. 1
